To all whom it may concern:

. 1 Be it known that I, AB AHAM .PAI.. .D1.N1,

a citizen of the United States, residing at SanFrancisco,in the county of San Francisconnd State of Californiznliai-e invented new and useful Improvements in Antitorpedo-Protectors, of which the following is a specification. 1

The object of the present invention is to provide means for protecting a ship from the attacks of torpedoes.

In the accompanying drawing, Figure 1 is a side view of a ship equipped with my improvement; Fig. 2 is a plan view of the same; Fig. 3 is a plan view showing the invention applied to a small boat or life boat; Fig. 4 is an enlarged detail side View show ing portion of the invention applied to a ship; Fig. 5 is a broken plan view of the same; Fig. 6 is a vertical crosssection of the same; Fig. 7 is a vertical cross-section showing the same in its extended or operative position.

Referring to the drawing, 1 indicates a ship to which my invention is shown as applied. The principal idea embodied therein is that of providing a hollow, narrow, elongated receptacle, the walls of which are made of sheet metal or other rigid material and which. is filled with compressed air. I here show on each side of the vessel two series of such receptacles or compressed air chambers. The inner series comprises receptacles 2 filled with compressed air through filling apertures 3, and having secured on their upper sides the lower ends of screws l. These screws extend through bearings 6 in brackets 7, secured, as shown at 8, to the sides of the vessel, and the receptacles are lowered into the water when required by turning hand-wheels 9, having hubs 11 resting upon the upper brackets and through which the screws 4: are screwed. They'are raised from the water by screwing said hubs on said screws.

The outer series of compressed air receptacles carry on their inner sides lugs 12 through which pass the up-turned ends 13 of crank arms 14 extending outwardly from vertical rock shafts 16 rocking in bearings 17 secured to the sides of the vessel, said rock shafts carrying on their upper ends collars 18 resting upon the upper bearings and having secured to their upper ends heads speofieamn bf Letters Patent.

19 having sockets 21, any one of which can be engaged by an end of a lever 22 to turn the rock shaIt. On the up-turned threaded ends 13 of the crank arms 1- are screwed nuts 23, which prevent the compressed air receptacles from rising from said ends.

/Vhen thevessel is traveling through a region in which there are no submarine tor,- pedoes, the receptacles of the inner series are drawn upwardly by means of the handwheels, while the receptacles ofthe outer series are moved inwardly toward the sides of the vessel by rocking the vertical rock shafts 16 by means of the levers at the top of said shafts, as shown in the lower side of F 2 and in full lines in Fig. 3. 1

When a danger zone is reached the receptacles of the outer series are first swung out ward by rocking the rock shafts 16, and then the receptacles of the inner series are low ered into the water.

When a torpedo strikes the outer side of one of the receptacles of the outer series and is thereby exploded, the force of the explosion fractures the outer side of said receptacle first and the escape of the C0111- pressed air from said receptacle reduces to some extent the force of the explosion exerted on the inner side of said receptacle so that the remainder of said force, being expended upon the water interposed between the receptacle and the side of the vessel is not sufficient to seriously damage the vessel. Moreover, safety is insured by interposing two such receptacles containing compressed air, which the explosion of the torpedo must fracture in sections.

In Fig. 3, I show a modification of my invention in which receptacles or protectors 26, similar to the receptacles 2 and 3, are applied to the sides of a life boat or other small boat. In this form of the invention said receptacles are secured to said sides of the boat by means of springs 27. These receptacles are of great value in lowering a life boat from a ship to the water. As is well known, the sides of life boats when low ered into the sea are often staved in by impinging against the side of the ship when rolling. In my invention this result is avoided by the interposition of the springsustained protectors or receptacles 26. Moreover, such hollow, air-tight receptacles are of great value in assisting the life boat to float, and in preventing it from being capsized, and increase the capacity ofthe lite boat more than fifty per cent.

I claim: I v

1. Means for protecting a vessel from the attacks of torpedoes comprising an inner and outer series of receptacles the walls of which are made of rigid sheet material, means for supporting the receptacles at a distance from the side of the vessel, and for moving the receptacles to and from the side of the vessel, and said means being located wholly outside the vessel.

2. Means for protecting a vessel from the attacks of torpedoes, comprising inner and outer series of receptacles the walls of which are made of rigid sheet material, means for extending the receptacles of the outer series to and from the sides of the vessel and means for raising and lowering the receptacles of the inner series.

3. Means for protecting a vessel from th attacks of torpedoes, comprising an outer longitudinal series of air-tight receptacles,

vertical rock shafts rotatably mounted adjacent to the side of the vessel, crank arms extending from their lower ends and pivotally connected to theinner sides of said receptacles, an inner series of air-tight receptacles, and means adjacent to theside of the vessel for raising and lowering the receptacles of the inner series.

4:. Means for protecting a vessel from the attacks of torpedoes, comprising an outer longitudinal series of air-tight receptacles, vertical rock shafts rotatably mounted adjacent to the side of the vessel, crank arms extending from their lower ends and pivotally connected to the innersides of said receptacles, an inner series of air-tight receptacles, vertical screws attached to said inner receptacles, and hand-wheels having hubs screwed around the screws for raising and lowering the inner receptacles, and means adjacent to the side of thevessel for raising and lowering the receptacles of the inner series.
